Pipe piles 42 in. in diam and up to 300 ft long are driven open end and filled with concrete to support high-level bridge across Irondequoit Bay near Rochester, NY; pipe was received in 40-ft lengths at staging area near bridge site, welded into 120-ft units, and coated with epoxy for length to be in mud stratum; floating template, with grids 5 ft below and 9 ft above water, was used to position 18 or 24 piles for each pier; crawler crane on barge set piles in template, then held 50,000-ft lb hammer for driving; additional 40-ft lengths of pipe were welded on as needed; mud was air-lifted out of pipes to clean sand, then tremie seal placed in pile; water was pumped out and concreting completed in the dry; floatable form was placed around pile cluster; 2 ft of concrete were tremied into bottom; then 8 ft thick cap was placed to 1 ft above water for support of superstructure.
